"None," returned Grace shortly. "She ordered me out of her room."

At this juncture Miriam Nesbit joined them. "What's the latest on the bulletin board?" she inquired, smiling mischievously.

"Don't laugh, Miriam," rebuked Grace. "Things are serious. Elfreda has some sort of engagement for Friday night with those two girls. She almost told me what it was, then changed her mind and invited me to mind my own business and leave her room. I'm going to try to find out something about Friday night and see that she gets fair play. After that I shall never trouble myself about her," concluded Grace, her voice trembling slightly.

"Don't feel so hurt at Elfreda's rudeness, Grace," soothed Miriam. "She doesn't mean half she says. She'll be sorry some day."

"I wish 'some day' was before Friday," replied Grace mournfully. "I wonder who else is to take part in this affair?"

"Watch Miss Wicks and Miss Hampton," advised Anne quietly.

"That's sound advice," agreed Grace. "I appoint you and Miriam as secret service agents. You must unearth the enemy's plans for Friday night."

"What will you do if we should happen to stumble upon them?" asked Miriam curiously.

"I don't know, yet," said Grace slowly. "It will depend entirely on what they are. Since we can't prevent Elfreda from going to her fate, we may be obliged to go along with her. If I were to ask you girls to drop everything and follow me on Friday night, would you do it?"
